5445 mm = 0.005445 km.

1000 mm = 1 m.

1 km = 1000 m.

Basically, you are moving the decimal place 6 times to the left.

First, compute the parentheses.

Next, do the exponents.

Then, do the multiplication.

Finally, subtract.

l = # of low terrain campers

h = # of high trail campers

$$l + h \le 30.$$

$$l \ge 10.$$

$$h \ge 5.$$

Yes, most likely.

Example: (2^2)^2 = 2^4 = 16.

Note, you just multiply the two powers together --> 2^(2*2) = 2^4 = 16.

Same for 3^(1/2)^(1/4) --> 3^(1/2*1/4) = 3^(1/8).

The total cost of the 3 computers is $900*3 = $2700. 

If the principal pays $98 per month for each computer, she will be paying $98*3 = $294 per month.

It won't take her 12 months to pay because $294*12 = $3528. 

If we round up $294 to $300 --> $2700 / $ 300 per month = 9 months. However, this is an overestimation, so she will need 10 months to pay.

Simply multiply both numerators and both denominators together to get 1 fraction.

Standard notation of 3.63 * 10^3

Move the decimal 3 times to the right since we have positive 3 ( ^3). That'll give you your answer!

A variable can be anything...p, q, r, s, t, u, v! x, y & z are more commonly used!

Yep, wonder how it'll be with 100+ people online! Crazy stuff then...maybe the website will be recognized by educational organizations!

Oh, yes, definitely. California has too much going on. Drought, earthquakes, wildfires...all of which are worsened by climate change. Yes, the forests are susceptible and hopefully can predict the next fires!

Interesting fact: One of my professors works on predicting fires in the Amazon...so cool although it sounds kind of odd.
